Under sjuksköterskeutbildning har diskussioner kring familjen och dess roll inom vården förts. Familjen har dock för oss förblivit ett diffust begrepp eftersom vi saknat en tydlig definition på vad en familj är. Vårt syfte blev därför att klargöra begreppet familj och dess komplexitet ur ett omvårdnadsperspektiv samt att studera familjebegreppet inom barnsjukvården. Inriktningen mot barnsjukvård gjordes då vi uppfattat familjen som central där. För att uppnå vårt syfte valdes en begreppsanalysmodell av Walker och Avant.

Abstract This Concept Analysis according to Walker & Avant (1995) studies the concept of uncertainty in the nursing context. It consists of four parts where uncertainty in general have been encircled in a semantic analysis (part one) and a qualitative content analysis consisting of an questionnaire, distributed to the staff members at one nursing and medicine institution, with an open question about the meaning of uncertainty (part two). The third part is a literature study of the nursing context to find out how uncertainty is described (part three). Part four is the actual concept analysis based on the three first parts. Uncertainty in the nursing context is an individual conscious experience witch is changeable and impressionable. It is chained together with its antecendents and consequences.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
